Background:
Community-acquired pneumonia is among the most common infections affecting ulcerative colitis and Crohn's disease patients. Data regarding epidemiology and outcomes of pneumonia in inflammatory bowel disease patients is lacking. We aimed to identify predictors of adverse outcomes among inflammatory bowel disease patients treated for pneumonia.
Methods:
This was a retrospective cohort study that included adult patients admitted to Sheba Medical Center for pneumonia between 2012 and 2018. Data was collected from an electronic repository of all emergency department admissions and included tabular demographic and clinical variables and free-text physician records. Pneumonia cases were extracted using the International Classification of Diseases (ICD-10) coding.
Results:
Of 16,732 admissions with pneumonia, 97 were inflammatory bowel disease patients (45 Crohn's disease; 52 ulcerative colitis). We found a similar rate of 30-day mortality among inflammatory bowel disease and non-inflammatory bowel disease patients (12.1% versus 11.3%, p = 0.824) and between Crohn's disease and ulcerative colitis patients (11.1% versus 11.5%, p = 0.947). There was an increased hospitalization rate among inflammatory bowel disease patients (92.8% versus 85.6%, p = 0.045), but similar hospitalization duration (4 versus 4 days, p = 0.384). Crohn's disease patients had a shorter hospitalization duration compared with ulcerative colitis patients (3 versus 5.5 days, p = 0.029). Bronchiectasis (adjusted odds ratio 60.95, 95% confidence interval 2.72-1364.39, p = 0.01) and opioids use (adjusted odds ratio 13.21, 95% confidence interval 1.29-135.18, p = 0.03) were associated with an increased 30-day mortality rate in inflammatory bowel disease patients.
Conclusion:
This is the first study to identify predictors of mortality in inflammatory bowel disease patients with pneumonia. The rate of mortality and hospitalization duration of stay were similar among inflammatory bowel disease and non-inflammatory bowel disease patients. Use of opioids and presence of bronchiectasis were associated with a higher risk of mortality in inflammatory bowel disease patients with pneumonia.

Bacterial Pneumonia Treatment
For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

01:30Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
